Hi, there! :)
Option C, "increased sarcopenia," is not a benefit of long-term physical training. In fact, increased sarcopenia is the opposite of a benefit, as it refers to the age-related loss of muscle mass and strength that occurs in individuals who do not engage in regular physical activity.
The other options listed are all potential benefits of long-term physical training:
- A. Increased myofibril size: Myofibrils are the contractile units of muscle cells. Long-term physical training can increase the size and number of myofibrils, leading to increased muscle strength and size.
- B. Improved psychological well-being: Regular physical activity has been shown to improve mood, reduce symptoms of depression and anxiety, and increase self-esteem.
- D. Injury prevention: Engaging in regular physical activity can help strengthen muscles, bones, and connective tissue, reducing the risk of injury during physical activity or in daily life.
Hope that helps! Good luck! ^_^
